ATLANTA, Idaho (KTVB)-Fire crews are working a new fire that is 'rapidly growing' , Boise National Forest officials said. Forest spokesman Dave Olson tells KTVB the Little Queens Fire is burning about six miles northwest of Atlanta.

Olson said the fire was estimated at 1,000 acres in size, and is rapidly growing. Because of its rapid movement, the fire is threatening public safety and has forced the closures for portions of the Boise and Sawtooth National Forest, Olson said.

According to Olson, the closed area within the Boise National Forest is generally bounded by the Middle Fork Boise River Road from Atlanta heading west to the junction with the Swanholm Road then north to Trail 057 then east to Forest Road 312 until it meets the Sawtooth Wilderness Boundary, and then south along the Wilderness boundary to Forest Road 205 at its junction with the Middle Fork Boise River Road.

The Middle Fork Boise River Road and Swanholm road are open for public use, but areas immediately inside the perimeter and the remaining roads and trails are closed. The cause of the fire is not yet known, but it is believed to be human-caused.
